Question

When 2/3 of a number is added to 10 the result is 5 more than the number find the number g?

Answer 1

`g-the\ number\\\\(2)/(3)g+10=g+5\qquad\text{multiply both sides by 3}\\\\2g+30=3g+15\qquad\text{subtract 30 from both sides}\\\\2g=3g-15\qquad\text{subtract 3g from both sides}\\\\-g=-15\qquad\text{change the signs}\\\\\boxed{g=15}`
